Ramp ranks first and Tipalti second among the AP platforms ranked here, and both cover all four vendor onboarding checks: collecting a W-9 or W-8, validating the tax ID, verifying bank details, and giving vendors a portal to enter their own information. Of 22 AP platforms, 10 collect tax forms in the product, 9 validate payee tax IDs, 9 verify bank details and 15 platforms give vendors a portal. Five credit all four checks: Ramp, Tipalti, Nanonets, Routable and Esker. Routable sells two of them as add-ons.

The [AP automation ranking](https://payablesbrief.com/best/ap-automation-software/) orders many of these platforms by cost, and onboarding is one input to that choice. A missing tax form shows up in January when the 1099 is due, and a changed bank account shows up in the payment run. Ramp lists a full price and Tipalti a base fee, and the [AP pricing index](https://payablesbrief.com/research/ap-automation-pricing-index/) sets both beside the other platforms.

## Onboarding checks by AP platform

Figures as of 12 November 2026. “Yes” means the vendor names the check. “Some plans” and “Add-on” mean it sits on a higher plan or costs extra. “Partial” means a control short of the check, such as an alert when a vendor’s bank account changes, or a portal in one product only. Partial and “No credit” rows earn no credit in the counts.

| Platform | W-9 or W-8 collected | Tax ID check | Bank-detail check | Vendor portal |
| --- | --- | --- | --- | --- |
| [BILL](https://payablesbrief.com/cost/bill-com/) | Yes | Yes | No credit | Yes |
| [Ramp](https://payablesbrief.com/cost/ramp/) | Yes | Yes | Yes | Yes |
| Melio | Some plans | Some plans | Partial | Yes |
| Nanonets | Yes | Yes | Yes | Yes |
| [Tipalti](https://payablesbrief.com/cost/tipalti/) | Yes | Yes | Yes | Yes |
| Routable | Yes | Add-on | Add-on | Yes |
| Vic.ai | No credit | No credit | Yes | Yes |
| [Stampli](https://payablesbrief.com/cost/stampli/) | Add-on | No credit | No credit | Add-on |
| [AvidXchange](https://payablesbrief.com/cost/avidxchange/) | No credit | No credit | Partial | No credit |
| [Airbase](https://payablesbrief.com/cost/airbase/) | No credit | Yes | No credit | Yes |
| [MineralTree](https://payablesbrief.com/cost/mineraltree/) | No credit | No credit | No credit | No credit |
| [Medius](https://payablesbrief.com/cost/medius/) | No credit | No credit | Partial | Yes |

| [Rillion](https://payablesbrief.com/cost/rillion/) | No credit | No credit | Partial | No credit |
| [Coupa](https://payablesbrief.com/cost/coupa/) | Yes | No credit | Yes | Yes |
| [Corpay](https://payablesbrief.com/cost/corpay/) | No credit | No credit | Yes | Yes |
| Basware | No credit | No credit | Add-on | Yes |

Tax ID checks split three ways. Ramp checks against IRS and VIES records, Airbase against government records for VAT numbers, and Melio against IRS records when a W-9 is uploaded, on Core, Boost and Unlimited. Brex lists TIN validation among the details captured on a W-9 upload. Routable lists TIN Validation and ITIN Validation as add-ons on Growth and Scale with no price.

Bank-detail checks are the least common of the four. Vic.ai verifies accounts through Plaid before a payment goes out. Coupa and Corpay verify as part of onboarding and on changes. Basware routes the check through Trustpair, which it lists as a separate product.

## Specialist tools that sit in front of AP

PaymentWorks, Trustpair, Eftsure and Kodiak Hub do not process invoices or run payment runs. They collect vendor details or check them before a vendor reaches the AP system, and all four quote only.

| Tool | W-9 or W-8 collected | Tax ID check | Bank-detail check | Vendor portal | Price |
| --- | --- | --- | --- | --- | --- |
| PaymentWorks | Yes | Yes | Yes | Yes | Quote only |
| Trustpair | No credit | Yes | Yes | No credit | Quote only |
| Eftsure | Yes | Yes | Yes | Yes | Quote only |
| Kodiak Hub | No credit | No credit | No credit | Yes | Quote only |

PaymentWorks matches every vendor’s TIN against IRS records, validates the address against USPS, and confirms account ownership against the payee’s authenticated identity before the account enters the ERP. Payees pay nothing for the standard registration. Eftsure’s portal requests documents such as W-9s, shows whether a TIN is valid, and verifies bank details before a payment is processed. Trustpair validates vendor tax IDs against official IRS records and returns Match, No Match, Invalid, Checking or Unconfirmed, and it validates bank accounts in 190 countries. Trustpair works inside the customer’s own onboarding form and has no portal of its own. Kodiak Hub is a supplier management tool with self-registration, and it describes no tax form, tax ID or bank check.

## The order: four checks, then price

Criteria, in priority order:

1.  Credit on four points: W-9 or W-8 collection, a tax ID check, a bank-detail check and a vendor portal.
2.  A full list price, then a base fee, then quote only.
3.  G2 review count, to order vendors with equal credit and equal price state.

Ramp and Tipalti credit all four checks, and Ramp’s full list price puts it first. BILL, Brex, Coupa and Zip credit three, with BILL and Brex ahead on a full list price. Airbase, Precoro, Stampli, Procurify and Corpay credit two. The ranking covers vendors with a cost record that credit at least two checks: Medius credits one, and AvidXchange, Emburse, MineralTree, Order.co, Paystand, Rillion and Yooz credit none. Nanonets, Routable and Esker credit all four checks, Melio credits three on paid plans, and Vic.ai and Basware credit two, but none has a cost record on this site, so they appear in the table and not in the ranking.

## What each check catches

A W-9 gives the payee’s legal name, tax classification and TIN, and it is the basis for 1099 reporting. A tax ID check compares that name and number with IRS records, which catches a mistyped number before a 1099 is filed. [Ramp](https://payablesbrief.com/cost/ramp/) and [BILL](https://payablesbrief.com/cost/bill-com/) both file 1099s, at $0.65 per IRS filing and $2.99 per form.

A bank-detail check protects the payment. The change that matters most is an existing vendor whose account number changes just before a payment run, and the platforms above split on whether they validate the new account or only flag it. The [invoice approval workflow guide](https://payablesbrief.com/guides/invoice-approval-workflow/) covers who signs off before the payment, and the [three-way match guide](https://payablesbrief.com/guides/three-way-match/) covers the vendor master data that matching depends on.

A vendor portal moves data entry to the vendor. It cuts the back-and-forth by email, and it only helps if the platform also checks what the vendor types.

## The ranking, with list price

### ![](/logos/ramp.png) 1. Ramp: Best for buyers who need all four checks without a separate onboarding tool

Ramp collects W-9 forms through Bill Pay and takes W-8 uploads on Plus and Enterprise. It checks US vendor TINs and EU VAT numbers against IRS and VIES records, verifies ACH account ownership on request, and runs automated fraud checks on bills before payment. Vendors sign up through a portal, and Ramp requires that sign-up by default. A request for payment and tax details goes to the vendor in one message, and the W-9, e-consent and bank details come back together.

### ![](/logos/bill-com.png) 3. BILL (Bill.com): Best for buyers who want tax forms and tax ID checks on every plan

BILL's W-9 Agent collects and verifies W-9 forms and shows as included on all four plans. BILL states that the agent attempts to verify the vendor's TIN after it collects the W-9, and a vendor can be invited to join BILL and manage their own bank information. 1099 e-filing is a separate charge at $2.99 per form, with lower rates at volume.

An optional third-party app, Sis Inside Coupa, adds another bank check.

### ![](/logos/zip.png) 6. Zip: Best for enterprise teams that screen new suppliers on tax ID, sanctions and bank details

Zip's supplier onboarding uses an AI-powered portal that guides suppliers through setup.

Zip names NetSuite, Sage Intacct, SAP S/4HANA and Oracle Fusion among its ERP integrations.

Precoro's Supplier Portal on the Automation plan lets suppliers upload documents, update catalogs, receive RFPs and purchase orders, and submit invoices. Attachments in the portal include bank statements and W-9 forms, and custom onboarding forms with approval workflows collect the rest. Core starts at $499 a month and Automation at $999, both billed annually.

Procurify's Vendor Portal lets vendors onboard themselves, manage their information and view purchase orders and invoices, and it costs vendors nothing.

    Ramp ranks first and Tipalti second, because each collects tax forms, checks tax IDs and bank details, and gives vendors a portal. Ramp's Free plan costs $0 per user a month. Tipalti's Accounts Payable plan starts at $99 a month.
    
-   Which AP platforms validate payee tax IDs?
    
    9 of 22 AP platforms do: BILL, Ramp, Melio, Brex, Nanonets, Tipalti, Routable, Airbase and Esker. Melio limits it to paid plans and Routable sells it as an add-on.
    
-   Which AP platforms verify vendor bank details?
    
    9 of 22 do: Ramp, Nanonets, Tipalti, Routable, Vic.ai, Basware, Esker, Coupa and Corpay. Routable and Basware sell the check as an add-on, and Basware's comes from its Trustpair product.
    
-   What is TIN matching?
    
    TIN matching checks a payee's taxpayer identification number and name against IRS records. It catches a W-9 with a wrong number before a 1099 is filed.
    
-   Do specialist vendor verification tools replace AP software?
    
    No. PaymentWorks, Trustpair, Eftsure and Kodiak Hub sit in front of an AP or ERP system and check or collect vendor details. The payments, approvals and invoice work stay in the AP platform.
